Texas Instruments TDC1000
The TDC1000 is a fully integrated analog frontend (AFE) for ultrasonic sensing measurements of level, fluid identification/concentration, and proximity/ distance applications common in automotive, industrial, and consumer markets. When paired with an MSP430/C2000 MCU, power, wireless, and source code, TI provides the complete ultrasonic sensing solution. The TDC1000 can be configured for multiple transmit pulses and frequencies, gain, and signal thresholds for use with a wide-range of transducer frequencies (31.25 kHz to 4 MHz) and Q-factors.| Part No. | TDC1000 |
